Filter by difficulty:
1
Acelepryn G (Chlorantraniliprole) - Premium Preventive Option
🟢 beginner 🔥 high Impact
Acelepryn G contains chlorantraniliprole and offers season-long protection with a single application, costing $40-80 per treatment for typical residential lawns. This premium preventive is low-toxicity and safe for bees when used correctly, making it ideal for homeowners prioritizing environmental safety while maintaining effective grub control. Apply in late spring or early summer before grubs hatch for optimal results.
Pro tip: Apply Acelepryn G in late May or early June when soil temperatures reach 55-60°F consistently—this timing ensures the product is in the soil when beetle eggs hatch, maximizing effectiveness.
2
Dylox (Trichlorfon) - Fastest Curative Solution
🟡 intermediate 🔥 high Impact
Dylox 6.2 granular insecticide kills grubs by both contact and ingestion, with visible results within 24-48 hours, costing $35-70 per application. This organophosphate-based curative works when you see active grub damage in late summer or early fall, making it the professional choice for emergency situations. However, trichlorfon is restricted in Massachusetts and several Northeast states due to water solubility concerns.
Pro tip: Water immediately after applying Dylox to activate the product—this step is critical and often overlooked. Pros always water within 30 minutes of application to achieve the fastest kill.
3
Scotts GrubEx1 (Chlorantraniliprole) - Budget-Friendly Preventive
🟢 beginner 🔥 high Impact
GrubEx1 contains chlorantraniliprole and is one of the most widely used preventive grub control products, costing $25-45 for a 10,000 sq ft application. This easy-to-apply spreader product provides long-term protection against multiple beetle species and is readily available at major retailers. Apply in late spring for season-long coverage without needing specialized equipment.
Pro tip: Scotts GrubEx1 works best on established lawns with good soil moisture—apply right before a forecasted rain or water lightly after application to help the product move into the soil where grubs feed.
4
BioAdvanced 24-Hour Grub Killer Plus (Trichlorfon) - Fast-Acting Alternative
🟡 intermediate 🔥 high Impact
This trichlorfon-based curative kills grubs on contact within 24 hours, costing $30-60 per application for typical lawn sizes. Ideal for visible damage and late-summer emergencies when you need rapid results, though it carries the same water-solubility restrictions as Dylox in certain Northeast states. Apply as soon as you spot grub damage for maximum effectiveness.
Pro tip: Apply BioAdvanced in early morning or late evening when soil temperatures are cooler—this reduces product breakdown and improves grub contact with the active ingredient.
5
Milky Spore (Bacillus Popilliae) - Long-Term Organic Solution
🔴 advanced 💪 medium Impact
This organic bacteria-based product specifically targets Japanese beetle grubs and can provide protection for up to 10 years with repeated applications, costing $25-50 per application. Milky Spore works slowly, taking 4-6 weeks to establish effective grub populations, but builds lasting soil immunity over multiple seasons. Not a quick fix for existing damage, but excellent for long-term prevention in established lawns.
Pro tip: Apply Milky Spore in late summer or early fall when soil temperatures are 65-80°F, and reapply annually for 2-3 years to establish a self-sustaining grub-suppressing population in your soil.
6
Beneficial Nematodes - Biological Control Option
🔴 advanced 💪 medium Impact
Beneficial nematodes (Steinernema species) are microscopic organisms that parasitize grubs, costing $40-80 per application for larger lawns. These organisms require consistent soil moisture and temperatures between 55-75°F to remain effective, making them best for spring and fall applications. Results appear gradually over 2-3 weeks as nematodes establish populations in the soil.
Pro tip: Apply beneficial nematodes in early morning or late evening and keep soil moist for 2 weeks after application—dry soil kills the nematodes before they can establish and reproduce in your lawn.
7
Imidacloprid (Merit) - Neonicotinoid Preventive
🟢 beginner 🔥 high Impact
This neonicotinoid-class insecticide is available in generic formulations and brand-name Merit, costing $20-40 per application for preventive grub control. Imidacloprid must be applied before grubs hatch (late spring), and the product requires soil uptake to be effective, making proper watering critical. It protects against multiple beetle species and is widely available at professional lawn care suppliers.
Pro tip: Imidacloprid requires consistent soil moisture for uptake—apply before a forecasted rain or irrigate within 24 hours of application to ensure the product reaches grub feeding zones.
8
Neem Oil - Organic Disruption Method
🟡 intermediate 👍 low Impact
Derived from the neem tree, this organic oil disrupts the grub life cycle and acts as a natural insect repellent, costing $15-35 per application when diluted properly. Neem oil must be applied multiple times (every 7-14 days) throughout the grub season to maintain effectiveness, making it labor-intensive compared to single-application products. Best used as part of an integrated pest management strategy rather than a standalone solution.
Pro tip: Mix neem oil according to label instructions and apply in early morning or late evening—UV light breaks down neem oil quickly, so daytime applications lose effectiveness within hours.
9
Carbaryl (Sevin) - Older Curative Carbamate
🟡 intermediate 💪 medium Impact
Carbaryl is an older carbamate-class insecticide available as a curative for active grub infestations, costing $20-40 per application. While effective when applied to visible grub damage, it has largely been replaced by faster-acting options like Dylox and requires proper soil moisture for effectiveness. Carbaryl is still available but less commonly recommended by professionals due to slower kill times (5-7 days).
Pro tip: If using carbaryl, apply it during cooler parts of the day and water thoroughly afterward—this older product works better in moist soil and requires more consistent application technique than newer alternatives.
10
Chlothianidin (Arena) - Moderate-Speed Neonicotinoid
🟡 intermediate 🔥 high Impact
This neonicotinoid shows some curative activity (grubs begin dying within 10-14 days) while maintaining preventive properties, costing $30-60 per application. Chlothianidin bridges the gap between fast-acting curatives and preventive options, making it valuable in regions where trichlorfon or carbaryl are restricted. Apply in late spring for prevention or early fall if you notice emerging grub damage.
Pro tip: Chlothianidin works best in the Northeast where trichlorfon restrictions apply—it's faster than standard neonicotinoids (10-14 days vs. 21+ days) while avoiding water-solubility regulatory issues.

Bonus Tip
Timing is More Important Than Product Choice
The most common grub treatment failure occurs from incorrect application timing, not product selection. Apply preventive treatments in late May through June when soil temperatures consistently reach 55-60°F, and curative treatments in late August through September when grub damage becomes visible. Watering immediately after application—whether preventive or curative—activates the product and improves results by 30-40% compared to dry applications.
